the result is 0, the condition is false. For example, the T condition is always true, and the EQ
condition is true only if the Z-bit condition code is true. Table 5-12 lists each condition test.
5.3.4 Using the TBL Instructions
There are four TBL instructions. TBLS returns a signed, rounded byte, word, or long-word
result. TBLSN returns a signed, unrounded byte, word, or long-word result. TBLU returns an
unsigned, rounded byte, word, or long-word result. TBLUN returns an unsigned, unrounded
byte, word, or long-word result. All four instructions support two types of interpolation data:
an n-element table stored in memory and a two-element range stored in a pair of data reg-
isters. The latter form provides a means of performing surface (3D) interpolation between
two previously calculated linear interpolations.
The following examples show how to compress tables and use fewer interpolation levels
between table entries. Example 1 (see Figure 5-7) demonstrates TBL for a 257-entry table,
allowing up to 256 interpolation levels between entries. Example 2 (see Figure 5-8) reduces
table length for the same data to four entries. Example 3 (see Figure 5-9) demonstrates use
of an 8-bit independent variable with an instruction.
Two additional examples show how TBLSN can reduce cumulative error when multiple table
lookup and interpolation operations are used in a calculation. Example 4 demonstrates addi-
tion of the results of three table interpolations. Example 5 illustrates use of TBLSN in surface
interpolation.
